Two changes to reservations:
1. Plumb through a prediction RPC to return the reservation system pressure and outstanding reservations for a list of projects. This is invoked from the instantiate page when loaded, using the projects the user has permission to create experiments in, the results are stored in a script global variable for someone else to make sense of. 2. When checking to see if a reservation can be accommodated, check with the admission control library first to see if the is a project limit on the type that would be violated. Need to do a little rearranging of the deck chairs in admission control library.
